Overview
The MAX3243CDBR is a Texas Instruments RS-232 interface integrated circuit featuring three drivers and five receivers in an SSOP-28 package. It operates on a single 3V to 5.5V supply with a typical quiescent current of 1mA. The device supports full-duplex communication at data rates up to 250kb/s. It includes a shutdown mode for power conservation and provides 15kV ESD protection on all lines. The component functions within a temperature range of 0°C to +70°C.
Feature Summary
- Integrates three independent line drivers and five line receivers for multi-channel serial communication.
- Includes a dedicated shutdown pin to minimize power consumption during idle periods.
- Provides robust electrostatic discharge protection rated at 15kV across all signal interfaces.
Applications
- Industrial control systems requiring reliable serial data transmission
- Portable battery-powered equipment utilizing low-power RS-232 links
- Modem and peripheral interface circuits
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the SSOP-28 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.
Selection Notes
Select this component when designing systems requiring three transmit and five receive channels within a compact surface-mount footprint. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range and utilizes a single 3V to 5.5V power supply rail.
Part Context
This part belongs to the MAX3243 family of multichannel RS-232 transceivers. It shares architectural similarities with other members like the MAX3243ECDBR but differs in maximum data rate specifications. The series is designed for applications needing multiple serial ports in space-constrained environments.
Replacement Considerations
The MAX3243ECDBR serves as a higher-speed alternative within the same package, offering 500kbps capability. Verify functional compatibility regarding pinout and electrical characteristics before substitution.
